(FR) SYSTÈMES ET PROCÉDÉS DE REJET DE CHALEUR SÈCHE AMÉLIORÉ PAR DES PARTICULES ET STOCKAGE THERMIQUE
Abstract
(EN)
The present disclosure is directed to dry cooling systems and methods that use particles to drastically increase air-side heat transfer for dry cooling. The systems may be used for the dry cooling of power plants and other industrial processes that require cooling. The systems further use moving particles to remove heat from a hot fluid or system through a heat exchanger of some form. This may be a fluidized bed or moving bed heat exchanger, or similar concept. The moving particles are then cooled easily with exposure to air, the ultimate heat sink. Particles enable thermal 'cold' storage that can increase cooling and power cycle efficiencies, especially in arid climates, by cooling particle storage at night. This novel cooling method decreases both capital and operating expenses compared with traditional air-cooled units by a factor of four and two, respectively.

La présente invention concerne des systèmes et des procédés de refroidissement à sec qui utilisent des particules pour augmenter considérablement le transfert de chaleur côté air pour un refroidissement à sec. Les systèmes peuvent être utilisés pour le refroidissement à sec de centrales électriques et d'autres processus industriels qui nécessitent un refroidissement. Les systèmes utilisent en outre des particules mobiles pour éliminer la chaleur d'un fluide chaud ou d'un système chaud à travers un échangeur de chaleur d'une certaine forme. Il peut s'agir d'un échangeur de chaleur à lit fluidisé ou à lit mobile ou d'un concept similaire. Les particules mobiles sont ensuite refroidies facilement avec une exposition à l'air, le dissipateur thermique final. Les particules permettent un stockage thermique "froid" qui peut augmenter les rendements de refroidissement et de cycle de puissance, en particulier dans les climats arides, par refroidissement d'un stockage de particules la nuit. Ce nouveau procédé de refroidissement réduit à la fois les dépenses en capital et de fonctionnement par rapport aux unités classiques refroidies par air par un facteur de quatre et de deux, respectivement.
